UNITED STATES PATENT OFFICE;

ALLAN JAY WAY,-OE ELLINGTON, NEW zEALANn CARBURiETE R 7 .To all whom it may concern.-

Be it known that I, ALLAN JAY WAY, a British'subiect, and aresident of 55 Lambton Quay, We lington, in the Colony of, New

Zealand, have invented certain new and useful Im rovements 1n Carbureters, of which the fol owing is a specification.

My invention relates to that class of apparatus for carburetingair and roducing a combustible gas for lighting and eating pur poses, in which'hot air is sent under pressure through a carbureter, where it is mixed with hydrocarbon vapor, and assing out is mixed with a further quantity hot. air before passin to the burners for consumption.

he object of my invention is to provide more efiicient means for heating the hydrocarbon (say fpetrol) lying in the carburetor,

and more e cient means for effecting the vaporization of the petrol and its mixture with the hot air admitted to the carbureter.

My invention consists in an improved construction of carbureter and heatmg apparatus and a special form of hot-air injector therefor, as hereinafter described, and particularly pointed out in the claims.

Referringto the accompanying drawings, in which similar, numerals, of reference indicate similar parts, Figure 1 is a part sectional side view'of a suitable form of apparatus with my im rovements applied thereto. Fig. 2 1s an on view of the carbureter with parts broken away to show someof the interior arrangements. Fig. 3".is an enlar ed longitue,

dinal sectional yiewpf my specia form-of injector. Fig. 4 1s an end view of the injector.

The general arrangement of the apparatus shown in Fig. 1 is as followsz-There is a framework (1) supporting a bellows. (2) or other suitable de lice for drawing air from the atmos here and drivingit under pressure through t e pipe (26) tothe air-heater (3) which may be of any known suitable type.

-The bellows is operated by'the shaft (4) driven by an engine or motor (not shown) of any suitable type. From the air-heater (3) the hot air passes throu h the pipe (5), portion being admitted to t e carbureter (7)-as I hereinafter described, through the short ipe (6) provided with the regu ating cook 10).

The carburetor (7) is supported on the frame-* work (1) and carries the petrol reservoir (8) which is in constant communication with the carburetor (7) by means of the pipes (9) there being therefore a constant suppl 0 liquid petrol (1.5) covering the bottom 0 the Specification of Letters Patent. y

carbureting chamber. Y An outlet pipe (115-- with, cook (12) leads the carbureted air or gas into the main (13) where it'is mixed with a further quantity of hot air coming from the .6

pipe (5) provided with cook (14), the mix ?v ture then passing to the'burners'for'con sumption.

Referring now to my i-mprovements:The

carbureter (7 has a liquid-proof false bottom (16) to the carbureting-chainber, on whichlies the liquid petrol 15,) and below the false bottom is a hot-water-chamber (17 which is continued at one end so as to extend beyond and a little up the side of'the car- 79 ylng on the false bottom (16)of the care bureting-chamber,' and raises it to the d'e-y 8o sired temperature.

Within the carbureting chamber transverse perforated bafile' plates (20) (21) (22) are provided, which are placed I preferably-as shownin Figs. 1 and'2. These baffle plates may be made of metal auze or perforated zinc or other metal, an are for the purpose of breaking up and completing the vaporization of |the petrol which to 1 Igether with hot, air 1s projected upon the afile lates b after d escribedl plete the mixture of the hot air with the petrol. The injector (23) is of special form,

the injector (23) as hereinc. The baflie plates also come and is illustrated more particularly In Figs. I t d 3 and'4. It is mounted in the Wall of carbureting-chamber, and connects with the om the pipe (5). The injector has a'ta- .g-ipe (6) bringing the hot air under pressure tegral' therewith and near its outlet a'backe roe wardly extending pipe (25) whichI term the] suction ipe. The injector is arranged-so that the ower end of its suction pipe (25) is normall immersed in the liquid petrol lying on the also bottom (16) of the carburetinghas chamber.

The operation of the apparatus shown is as Y follows :The water in the hot-water-chamber (17) is kept'heated by means of the burner (19) so as to raise to the desired p the temperature of the liquid petrol (15) ying on the false bottom (16) of the carburet Oint no ction is, mounted below the 7 5 i ling-chamber The bellows (2) is set in motion,- s'up lying air under pressure through the pipe its to the air-heater (3)Wh61 it is heated, the hot. air passin upthe pipe (5) A andportion being drawn oif by the short pipe 1, (6). The cock (10) being opened to the deits mixture with hot air.-

sired' extent, hot-air rushes into the injector (23), the taperedrnozzle of which ijicreases the pressure asthehot air passes onward the passage of the hot air causmg petrol-to be drawn up from the bottom (16) of the carbureting-chamber through the suction pipe into the nozzle (24) this petrol mingling in the mouth-of the nozzle with the hot air and dischar ing therewith againstthe baffle plates (20) %21) (22) which break it rol and complete the vaporization of the petrol and The carbureted air or gas isled off by the pipe (11)- and, the cooks (12) and (14) havin been opened, it passes on to the burners or consumption,

' receivingon the Way an additional mixture of hot air from the pipe (5).

While I have shown my improvements applied to one particular form (gt-apparatus,

pered nozzle for introducing air to said chamher, said nozzle having a branch extending rearwardly and downwardly from adjacent the'outlet end thereof, -the lower end of said branch being immersed in the petrol.

In testimony whereof I. have signed my name tothis specification in thepresence of two subscribing Witnesses;
